3.24.4 bars

‘small‘ is a synonym for 0.0, and ‘large‘ for 1.0.
The default is 1.0 if no size is given.

The keyword ‘fullwidth‘ is relevant only to histograms with errorbars.
It sets the width of the errorbar ends to be the same as the width of the
associated box in the histogram. It does not change the width of the box
itself.

The ‘front‘ and ‘back‘ keywords are relevant only to errorbars attached
to filled rectangles (boxes, candlesticks, histograms).
